As part of perf they become GPLv2. this change breaks compilation, which is probably fixed later on in patchset CC util/jevents.o util/jevents.c: In function ‘lookup_msr’: util/jevents.c:140:2: error: unknown type name ‘bool’ static bool warned; ^ util/jevents.c:148:12: error: ‘true’ undeclared (first use in this function) warned = true; ^ util/jevents.c:148:12: note: each undeclared identifier is reported only once for each function it appears in util/jevents.c:149:3: error: implicit declaration of function ‘pr_err’ [-Werror=implicit-function-declaration] pr_err("Unknown MSR in event file %.*s\n", ^ util/jevents.c:149:3: error: nested extern declaration of ‘pr_err’ [-Werror=nested-externs] cc1: all warnings being treated as errors make[1]: *** [util/jevents.o] Error 1 make: *** [all] Error 2 jirka -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
